как реализовать вывод всех подкатегорий в speedbar?

        $category_id = intval( $row['category'] );

        $category_ids = explode(",",$row['category']);

function get_breadcrumbcategories($id) {
    
    global $cat_info, $config, $PHP_SELF;
    
    if( ! $id ) return;

    global $category_ids;
    if($category_ids AND count($category_ids)>1){
        $urls = array();
        foreach($category_ids as $v){
            if( $config['allow_alt_url'] ) $urls[] = "<span itemscope itemtype=\"http://data-vocabulary.org/Breadcrumb\"><a href=\"" . $config['http_home_url'] . get_url( $v ) . "/\" itemprop=\"url\"><span itemprop=\"title\">{$cat_info[$v]['name']}</span></a></span>";
            else $urls[] = "<span itemscope itemtype=\"http://data-vocabulary.org/Breadcrumb\"><a href=\"$PHP_SELF?do=cat&amp;category={$cat_info[$v]['alt_name']}\" itemprop=\"url\"><span itemprop=\"title\">{$cat_info[$v]['name']}</span></a></span>";
        }
        return implode(", ",$urls);
    }
